termini

I'm a little stuck... Click here to teach me more about this clue!

'route ends' is the definition.
'termini' can be an answer for 'ends' (terminus is a kind of end). I'm not certain of the 'route' bit.

'featured by litter minimisation' is the wordplay.
'TERMINI' is hidden within the letters.
But, I'm uncertain how the hidden word is indicated.

Can you help me to learn more?

(Other definitions for termini that I've seen before include "ends of lines" , "Line ends" , "Rail stations mainly in city centres" , "End points of rail or bus routes" , "Rail, bus stations" .)

I've seen this clue in the Sydney Morning Herald.
